DIETZ & METZGER COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.-

To all whom it may concern:

Be it known that I, FREDRICK WILLIaM ROCHELLE, a citizen of the Lnited States,

residing in Philadelphia, Pennsylvania, have taining hooks and.of the mechanism for operating't-he same in accordance with my invention; Fig. 2 is an enlarged view of the hook and its carrier, partly in side elevation and partly in longitudinal vertical section; Fig. 3 is a lan view of the same withthe supporting ar removed; Fig. 4 is a rear view on a smaller scale, of two of the hook carriers and of the bar upon which they are mounted; Fig. 5 is a plan view of the same,

and Figs. 6 and 7 are views illustrating the operation of the hook in connection with a pile wire.

The invention forming thesubject of the aforesaid patent, No. 529,615, consisted in the use of a series of hooks for engaging the pile wires in succession, as they were beaten up and holding such wires in an upright position during the interweaving of the backing weft threads with the pile warp threads loo ed over the wires.

n the patented device the retaining books were provided with resilient shanks or stems secured to a rigid bar extending across the loom above the breast beam, and the hooks were normally so disposed as to engage the wires and were lifted by each wire as the latter was forced under the hooks in being beaten up to its place in the web by the action of the reed. It has been found in practice that the imposition of this duty upon the pile wires had a tendency to defeat, in a measure, the purpose for which the retaining hooks were designed, and my invention has therefore been devised with the view of overcoming this objection, one feature of my invention consisting in imparting a positive raising and lowering movement to the hooks in order that each pile wire can be beaten up 'PILE-WIRE SUPLBORTER FOR LooMs.

are raised and therefore without any interi fercnce with said hooks, the latter being then warp threads which have been looped over the wire, the hooks being then again raised prior to the insertion of a succeeding wire.

,/ In Fi 1 of the-drawing, 1 represents one of the wire-retaining hooks, which has a stem or shank 2, terminating in a head 3, slotted, as at 4, for the reception of a bolt 5, whereby said head is secured to a projecting arm 6 fitted so as to be free to rock or swing to a limited extent in a cup 9 which is secured to the underside of a rocking bar 10 mounted in suitable bearings 1 1 on the breast beam or other available member of the loom, any lateral swinging movement of the hook independently of the block 7 being prevented by reason of the engagement with the slot 4 of a log 12 on the upper face of the arm 6 of the block.

One end of the rocking bar 10 is rovided with a crank 13 connected by a r01 14 to a. lever 15, the latter being intended to be fulerumed upon the fixed frame of the loom at any convenient point and being connected by an adjustable rod 16 to a lever 17 likewise in tended to be conveniently fulcrumed upon the fixed frame of the loom, this-lever 17 having an anti-friction roller 19 which is set ed upon by a cam 20 on the cam shaft 21 .of the loom, said anti-friction roller being maintained at all times in contact with the periphery of the cam 20 by reason of the action upon the lover of a coiled spring 22 which, at one end, engages a link 23 on the lever and is intended to be secured at the other end to a fixed lug on the loom frame, being provided with a threaded rod 24 and nuts '25, in order that the tension of the spring 22 may be regu lated as desired.

The cam 20 is designed to impart such .rockin movement to the bar 10 as will effeet a lifting of the hooks 1 during the time that each pile wire is being beaten up, the hooks bein then lowered into engagement with the piIe wire and retaining their position during the insertion and beating up of i the weft thread or threads whereby the tying l of the pile warp threads into the backing fabj rie is effected.

Vertical adjustment of the hooks in respect 1 to its position in the web while the hooks lowered so as to engage the pile wire and re tam it in position during the tying in of the upon a cylindrical block 7, the'latter being limited extent in either direction in order to y means of a spring 26 on each side of thesame,but said hook can yieldlaterally to a insureits entrance atween the bars of the reed when the latter is beating up, since, if the forward end of the hook should ha )pen to strike the advancing edge of. either of t e reed bars, it can yield to one side or the other sufficiently to escape the same and thus prerent injury either to the reed bar or hook, which might be caused if said hook opposed a rlgid resistance to the reed.

1. The combination, in a loom for wearing pile fabrics, of a hook constructed to engage the upper edge of the last inserted pile wire and retain the same in position while the loops are being formed over the same, with means for raising and lowering said hook, whereby it can be moved to position free from engagement with the upper edge of the wire when the same is being beaten up.

2. The combination, in a loom for wearing pile fabrics, of a series of hooks, each con structed to engage the upper edge of the lastinserted pile wire and retain the same in position while the loops are being formed over the same, a bar carrying said hooks, and means for rocking said bar to cause the hooks to engage with or be disengaged from the wire.

3. The combination, in a loom for weaving pile fabrics, of a series of hooks constructed to engage the upper edge of the last inserted ile wire, and retain the same in position while the loops are being formed over the same, a bar carrying said hooks, and means for rocking said bar, said ineans having an I adjustable element whereby the position of the hook in respect to the upper edge of the wire can be var1ed.

' 4. The combination of a pile-wire-reteininghook, with a laterally yielding mount therefor.

5. The combination of a pile-wire-retaining hook, with a mount therefor free to yield laterally m either direction.

6. T he combination of a pile-wire-retaining hook, with a mount therefor opposing yielding resistance to the lateral movement of the hook.

7. The combination of a pile-wire-retaining hook, with a mount therefor opposing *ielding resistance to the lateral movement of the hook in either direction.

8. The combination of a pile-wire engaging hook, a mount therefor free to yield latorally, and a rocking bar carrying said yielding mount for the hook.

9. The combination of a pile-wireengaging hook, a block carrying the same, a cup in which said block is mounted so as to have a slight swinging in vement, and a rocking bar to which said cup is isecured.

10. The combiiiat'on of a pile-wire-engag ing hook, a block carrying the same, a cup in which said block ismounted so as to have a slight swinging movement, a rocking bar to which-said cup is secthier \and springs tending to maintain said bl n a central position. \1 In testimony whereof, iave signed my name to this specification, in" tliepnesence of two subscribing witnesses.
